Design/methodology/approach: Initially, we defined ‘extension system’ as a wide range of actors integrating resources with the aim of co-producing value (not for but with) farmers. To capture the value flow within this constellation of actors we distinguished between the notion of ‘value in production’ – i.e. the value embodied in service offerings – and the value emanating when service content is used in real settings or ‘value in use.’
Findings: Our approach revealed that, despite their structural and organizational differences, the ES in the three countries share common problems arising from a limited focus on the issue of value in use.
Practical implications: The application of a systemic approach – seeing farmers as co-creators and not as end-users of extension services – in the evaluation of ESs contributes to better understand the complexity of value flow within the system and can strengthen extension systems’ effectiveness.
Theoretical implications: The present study, by reconsidering traditional evaluation approaches and by focusing on value co-production, offers an alternative value-centric framework for the conceptualization of extension services and points out to the need for refining the evaluation criteria of ESs.
Originality/value: Our work, by emphasizing the reciprocal creation of value within ESs, and by adding the concept of value in use, offers a new systems approach worth considering when evaluating ESs within different organizational and sociocultural contexts. 相似文献
Purpose: The purpose of this study was to identify preservice teachers’ ideas about how to increase students’ long-term interest in science.
Sample: The participants were 235 preservice primary teachers and 33 preservice secondary science teachers.
Design and Methods: Data collection was by questionnaire, interview and classroom observations.
Results: It was found that participants in both primary and secondary groups had very similar ideas about how to develop pupils’ long-term interest in science. These ideas mainly involved the use of hands-on activities, making science relevant, and using student-centred strategies or electronic media to make lessons fun and to enhance engagement. These can be interpreted as representing sources of situational interest (i.e. short-term interest arousal). These ideas broadly parallel the current theory on interest development, such that long-term individual interest is thought to develop from repeated experiences of short-term, situational interest.
Conclusion: The participants’ ideas in this study were intuitive, because they were not derived from an understanding of theory, but rather from their personal experiences of interest arousal at university, school and practicum. Nevertheless, their ideas were workable for a practitioner, because they broadly paralleled current theory on interest development. 相似文献
Purpose: This qualitative case study investigates a primary science teacher’s TPACK development in the context of two interdependent learning spaces: a joint-school and a within-school professional learning community. The school’s organizational and sociocultural influences on teacher learning are also examined.
Participant: Teacher Sean (pseudonym) embarked on a science innovation project after two years of teaching in a Singapore mainstream school. He was tasked to integrate mobile-based inquiry learning and visible thinking pedagogical approaches, and to pilot the designed lessons for a primary three class.
Design and methods: A case-study approach involving multiple sources of data with cultural historical activity theory as the analytical lens was employed, to unpack the complementary and contradictory interactions across different interrelated activity systems. The purpose was to understand the (mis)alignments within and between the two professional learning communities.
Results: The findings indicate that Sean’s (subject) learning from the joint-school professional learning community to the within-school professional learning community faced multiple tensions that hindered his TPACK development (object). He faced difficulty in manipulating tools (technology and visible thinking routines) to translate the joint-school co-designed lessons into classroom implementation. Additionally, the volatility of the school’s organizational routines (rules) and the lack of communicative leader–teacher partnership (division of labor) did not afford sufficient infrastructure or instructional support.
Conclusions: Interactions between the teacher’s personal and contextual factors inhibited the designed TPACK from being implemented successfully. For ambitious pedagogical undertakings as illustrated in this case, more perceptive and synergistic organizational design thinking is needed to support beginning teachers’ TPACK development. 相似文献
The story of the accusations launched at Gerry Adams introduces some questions regarding the authenticity and authorisations of archives. This story evokes the competing archives of childhood and the possibility of critique arising from recognition of the tensions between competing archives. The article addresses the complications of archives, counter-archives, archaeology and genealogy as records and research materials. The writer uses Cixous’s notion of ‘ecriture feminine’ as a way of escaping the linearities of archivalism. 相似文献
Design/Methodology/Approach: The study engaged 30 farmers’ children in high school level from the provinces of Pangasinan, Isabela, Camarines Sur, Iloilo, Bukidnon, and Davao del Norte from November 2016 to October 2017. They interacted with the research team (the authors) and the RCM-SMS platform that sends text messages regarding fertilizer recommendations. A staff member from the Agricultural Training Institute (ATI) also called the students for some follow-up questions. The research team conducted three rounds of interviews with the students concerning the messages and calls that they received and what they did with the information.
Findings: This study finds that farmers’ children can perform infomediary roles quite effectively. Academically excellent children and those involved in farm work performed best.
Practical Implications: The study provides guidance on similar initiatives tapping young people in agricultural development.
Theoretical Implications: This paper finds that while Community Youth Development (CYD) Theory provides a powerful lens in understanding community and youth development intersections, some identified outcomes may overlap and may not be very easy to observe. Hence, the identified outcomes may be revisited for clarity and to make them more all-encompassing.
Originality/Value: The paper documents actual parent-child interaction when the latter is mobilized to serve as an infomediary to access nutrient management-related information on rice. 相似文献
Method: Using grounded theory methodology, 12 participants were interviewed about the meanings and roles of valued material objects following a residential transition. Older adult participants lived in either their own home or a care home.
Results: The model entails two core categories, “threats to identity” and “objects and identity continuity” along with four explanatory concepts, “moving and identity discontinuity”, “connections across time”, “attachments to others”, and “preserving self and ancestors in the memories of the next generation”.
Discussion: Objects were described to have important personal meanings which helped people maintain a sense of identity continuity following residential transition. They were associated with comfort, security and life review processes, which support identity continuity later in life.
Conclusion: Moving house later in life can threaten a person’s sense of self. However, material objects can help maintain a sense of identity continuity through reminiscence and life review processes. Implications for community and residential care moving house transitions are discussed. 相似文献
Design/methodology/approach: A review of the literature highlights that entry to a working life in agriculture has been characterised by protracted farm succession processes; a strong association between being a farmer and owning land in the family name; lingering male identities esteeming manual labour; and a pragmatic need at farm level for manual work. The abolition of milk quota in 2015 was predicted to catalyse expansion of production on dairy farms with an increase in milk production; accompanied by a demand for qualified personnel. The BNIM method was employed.
Findings: Results confirm that agricultural education is perceived and experienced as offering new pathways for young farmers to enter the occupational category of ‘farmer’, helping to manoeuvre around the constraints of non-inheritance. The students’ narratives evidenced managerial identities, being strongly influenced by encountering management approaches through their agricultural education. All students desired to eventually own a farm someday and to be to employed as a professional dairy farm manager was a perceived as an intermediary goal.
Practical implication: Discontinuation of the traditional family farming model based on family farm/land ownership is not imminent even among a cohort qualified to become employed dairy farm managers.
Theoretical implication: This paper contributes to theoretical framework which highlights the shift in farmer masculine identity and the career trajectory of graduates of specialised agricultural education programmes. 相似文献
Purpose: To identify the evolution of students’ conceptions regarding the nature of sound and its properties (frequency, intensity and frequency spectrum) through a teaching-learning sequence (TLS) about sound phenomena in an authentic musical context. The described TLS consists of three activities aiming students to correlate the properties of sound waves (frequency, intensity and frequency spectrum) with its perceptive characteristics (pitch, loudness and timbre) via the use of smartphone applications.
Sample: Eight students, in the second year of their studies in the Department of Primary Education of the XXX University.
Design and methods: Students’ perspectives on sound and their progression are investigated through a teaching experiment design. Data are collected by recording students’ interviews. Due to the explorative nature of the research qualitative methods of content analysis are used.
Results: The results show that the students’ perspectives on sound evolved, as students managed to consolidate links between their everyday experience of sounds and the underlying science concepts as frequency, intensity and frequency spectrum. The authentic environment and the use of the smartphone’s applications were key factors for the success of the teaching experiment. The interaction with the activities shifted student’s conceptualizations closer to the scientific ones, by communicating every day sound experiences with their scientific interpretation. 相似文献
Purpose: This study aimed to develop a mediational model providing the factors accounting for Taiwanese junior high school adolescents’ science learning self-efficacy (SLSE), especially from the perspectives of both interpersonal and intrapersonal factors.
Design: We therefore proposed a mediational model to delineate the relationships among students’ perceived responses to capitalization attempts – science learning (PRCA-SL), science learning hardiness (SLH) and SLSE by conducting structural equation modeling (SEM).
Sample: A total of 1,170 junior high school students in Taiwan were invited to take part in the study.
Results: The results confirmed our hypothesis that students’ PRCA-SL fostered their science learning hardiness, which in turn contributed to their science learning self-efficacy.
Conclusions: The findings confirmed the mediational model wherein science learning hardiness completely mediated the relationship between PRCA-SL and science learning self-efficacy. 相似文献
Purpose: The aim of this study was to explore students’ perception of teachers’ feedback given on their texts in two genres, and to suggest how writing training and feedback-giving could become more efficient.
Sample: In this study were included 44 degree project students in biology and molecular biology, and 21 supervising teachers at a Swedish university.
Design and methods: The study concerned students’ writing about their degree projects in two genres: scientific writing and popular science writing. The data consisted of documented teacher feedback on the students’ popular science texts. It also included students’ and teachers’ answers to questionnaires about writing and feedback. All data were collected during the spring of 2012. Teachers’ feedback, actual and recalled – by students and teachers, respectively – was analysed and compared using the so-called Canons of rhetoric.
Results: While the teachers recalled the given feedback as mainly positive, most students recalled only negative feedback. According to the teachers, suggested improvements concerned firstly the content, and secondly the structure of the text. In contrast, the students mentioned language style first, followed by content.
Conclusions: The disagreement between students and teachers regarding how and what feedback was given on the students texts confirm the need of improved strategies for writing training and feedback-giving in science education. We suggest that the rhetorical meta-language might play a crucial role in overcoming the difficulties observed in this study. We also discuss how training of writing skills may contribute to students’ understanding of their subject matter. 相似文献
Purpose: This study explores STEM students’ encounters with an interdisciplinary first year. Specifically, motivational patterns towards learning in two introductory courses followed by students from multiple study programmes are investigated.
Sample: 173 Danish undergraduate students enrolled in three science programmes: biomedicine; biochemistry and molecular biology; and physics.
Design and methods: Within the framework of Self-Determination Theory, a measure of autonomous and controlled motivation forms the basis for quantitative analyses (n = 173). A qualitative thematic analysis of students’ open responses further supplements and gives nuance to the findings.
Results: The motivational pattern of physics students is found to differ significantly from that of biochemistry and molecular biology (BMB) students and biomedicine students. The comments reveal that some students struggle to realise the relevance of the course content for their chosen study programme to an extent that makes them reconsider their study choice.
Conclusions: The study offers input to the discussion of how to present inter- and/or multidisciplinarity to students and points to implications on two levels: curriculum design and course content. The findings are of importance to educational planners, decision-makers and teachers dealing with the motivational range that exists within their courses. 相似文献
Purpose: In this study, we investigated how students’ mental models about one-dimensional expansion can be extended for purposes of running mental simulations about expansion along two dimensions.
Sample: To that end a pretest-posttest quasi-experiment has been conducted, with 100 students in the control group and 95 students in the experimental group.
Design and methods: Whereas control group students received traditional instruction with a focus on formal representations, in the experimental group the students were led to draw an analogy between heating of a straight rod and a circular rod of same length, whereby the internal structure of the rods was represented by springs.
Results: Eventually, it has been found that students from the experimental group were significantly more successful at predicting the effects of thermal expansion, especially within contexts of objects with holes.
Conclusion: Analogies and extreme case reasoning can be effectively used for helping the students to correctly transfer their mental models about one-dimensional expansion to situations that require reasoning about expansion along two dimensions. 相似文献

These lines from a popular song of the nineteen forties sum up what was for many women a new reality. This paper identifies the space at the sewing machine as mother's space and the sewing machine as an important element in the psychological and financial liberation of the woman, here the Caribbean woman of the twentieth century. Evidence in support of this claim is offered predominantly from Caribbean creative writing, where artists have noted the importance of that invention in the lives of their mothers and in the achievements of their families. 相似文献
What value is added for writer and reader by intentionally keeping personal learning part of public researching? When a practitioner attends conscientiously to ‘the relationship with their research,’ does it make a difference to their learning and researching? If it does, can this difference also make a difference to the reader …? This paper addresses these kinds of queries from the standpoint of ‘scholarly practice,’ the research undertaken by mature managers and professionals who account in text for initiating and sustaining change within their complex contexts of work. Through exploring a variety of learning frames, the authors identify the distinctive opportunities and challenges in practice-led enquiry, and raise implications critically for the researching professional as well as for their ‘enablers’—the academic supervisors or fellow action-learning set members—who support and challenge the efforts of scholarly practitioners to make sense of and explicate their action. Revans's praxeology of action-based learning (systems alpha, beta and gamma) is extended as a research analogue for practice-led knowing. Ontological, methodological and epistemological perspectives are progressively deployed to examine critically the essentially reflexive nature of scholarly practice. The authors depict challenges in scholarly practice of establishing focus, incorporating others' thinking alongside one's own and asserting one's own voice. The paper concludes by warning of two ways in which enablers can unwittingly hijack the purpose of practice-led research. 相似文献
